The TreeMap component provides built-in compliance with WAI-ARIA specifications. The WAI-ARIA accessibility supports are achieved using attributes such as aria-label. It helps to provide information about elements in a document for assistive technology.
Aria-label:
This attribute provides text label with some default description for the following elements in TreeMap.
| Element | Default description |
| TreeMap container | - |
| TreeMap Title | Reads the TreeMap title |
| TreeMap Subtitle | Reads the TreeMap subtitle |
| Legend Title | Reads the legend title |
You can change this default description using the description property available in TreeMapLegendSettings, TreeMapTitleSettings, TreeMapSubTitleSettings, and SfTreeMap tags. It helps screen readers to read for assistive purpose.
